Mobile ad-hoc networks operate in the absence of any supporting infrastructure. The absence of any fixed infrastructure in mobile ad-hoc networks makes it difficult to utilize the existing techniques for network services, and poses number of various challenges in the area. The discovery and maintenance of secure route is the most flinty challenge. In this thesis, we first deliberate and implement one secure routing protocol SAODV and study its performance under different scenarios. Then we carry out a number of experiments using NS-3 to compare the performance of AODV, SAODV in terms of security level and routing discovery time under different setups. From these experiments, we can see that performance of AODV and SAODV and Aridane.

Peroxodisulfate was simply supported on a weakly basic ion exchange resin by elution of a column containing the resin with an aqueous potassium peroxodisulfate solution. Resin supported peroxodisulfate was used for mild and selective ?-iodination of 1,3-dicarbonyl and ?,?-unsaturated carbonyl compounds in the presence of molecular iodine in acetonitrile at room temperature. Also direct and efficient iodination of activated aromatic compounds was performed in acetonitrile under reflux conditions.

Code layout is an important factor that determines the performance of any application. For branching intensive loops where decisions have to be made among several branching paths (as in real time systems), an optimized layout of the conditional statements can increase the performance largely. Current methods can predict branches dynamically using speculative execution which can be resource intensive. Static branch prediction techniques are not as accurate. In this work a compiler based optimization for branching instructions by code reordering has been proposed. The proposed design consists of a code reordering component that along with the compiler can dynamically generate layout-optimized code, by reordering the conditions in the source program. The reordering is done base on dynamic run-time execution patterns. Based on the current execution pattern and the history, the most optimal program can be run, minimizing evaluation of conditions.

Investor protection is one of the essential roles of authorities to make them involved in the financial market. Stock market plays a predominant role in the financial market. Investor protection helps to develop the market so that mobilization of funds can be increased. Increase in market potential is another way to increase growth of the market. Every nation has own legislation frameworks for stock market which is varying from country to country. In India, there is a strong need for an effective regulation for stock market so that the investors’ interest can be safeguarded in a better way. In order to regulate stock market and the participants of stock market there are various legislations are framed. It minimizes the risks and protects the investor. An attempt has been made to review the Indian legislations which are standardizing the Indian stock market and the legal formalities to be carried out by the market players.

The pyonephrosis is a suppurative process of the urinary tract kidney leading to a rapid and complete loss of kidney function The surgery is difficult with an early mortality and morbidity The emergency surgery is persistent sepsis or the presence of complication. We report 19 cases of pyonephrosis treated in our service

At present, when contemporary organizations are seeking novel and original initiatives to gain a competitive position in the market, reverse logistics is one of the worth mentioning domains which has been distinctly recognized in this regard lately. As the field is in introductory phases with respect to large scale managerial concerns, it is facing certain difficulties and barriers in conveying the desired benefits for organizations. This study has made an attempt to put all the identified barriers together in the form of a mode. The study has been extended to review these barriers and also confer the unique approach to manage these barriers by conceptualizing the minimum number of managing factors. The study is based on theoretical grounds of introducing top management support, information support system and formalization of the reverse logistics programs to remove problems faced by the successful intervention of reverse logistics.

The participants of all the four groups were compared with respect to their mental health. The result indicated that androgynous women showed better mental health than that of sex-typed women. Women with high sense of efficacy showed better mental health and scored higher in almost all dimensions of mental health than less-efficacious women.

There are seventy Oraon families have been studied for the present paper.. The study area is located West Bengal and Bangladesh Border site. The Sadder Para (Oraon) of the Village Dhuluni is unit of the present study. The segments or hamlet of the village is completely composed with homogenous population. Only Oraons are living in this area and still now practice their traditional way of life with affluence of modernization. They had been living since hundred years. The people of the -study area- said that they came from Bangladesh due the Indigo tax. Their ancestors were come for cutting the jungle. The opinions of the villagers that their ancestors were not able to pay the Indigo tax and the British emperors not agree to release hard taxation on them. So they had come and find new jobs by the moneylenders or Zaminders in this locality.

This paper provides the designing of mosfet with different materials and compare which material is better for the designing. In previous time the mosfet is design by the combination of silicon and silicon oxide now we are using gallium arsenide and silicon dioxide as one combination and gallium arsenide and silicon nitride as another combination.

Silver nanoparticles dispersed in water in presence of trisodium citrate have been prepared and characterised. Aqueous solutions of silver nitrate and trisodium citrate were mixed in various proportions and heated at 30oC for 3 hours. The nanoparticles of silver dispersed in water in presence trisodium citrate were characterised by UV-visible absorption spectra, X-ray diffraction, EDX, and SEM. Nano-silver dispersed in water based nanofluids may used to increase thermal conductivity of fluids.
